DAYTONA BEACH, Fla. – Mitt Romney responded to President Barack Obama's latest attack, accusing the GOP nominee of forgetting and shifting his positions on issues on Friday night by calling out the Obama campaign for resorting to "petty attacks and silly word games" in the final three weeks of the campaign.

"Have you been watching the Obama campaign lately?" Romney asked a crowd of several thousand supporters at an outdoor event Friday night. "It's absolutely remarkable. They have absolutely no agenda for the future. No agenda for America. No agenda for a second term. It's a good thing they won't have a second term."

"They've been reduced to petty attacks and silly word games. Just watch it. The Obama campaign has become the incredible shrinking campaign," Romney said.

Romney's counter came after Obama unveiled a new line of attack at a rally earlier Friday in Virginia, coining the term "Romnesia" to describe satirically how Romney might have changed positions on issues by forgetting his past stances over the years.

“He's changing up so much -- backtracking and sidestepping. We've got to name this condition that he's going through. I think ... I think it's called 'Romnesia'. Now, I'm not a medical doctor but I do want to go over some of the symptoms with you. Because I want to make sure nobody else catches it,” the president said.

“If you say you're for equal pay for equal work, but you keep refusing to say whether or not you'd sign a bill that protects equal pay for equal work, you might have Romnesia,” Obama said to laughs. “If you say women should have access to contraceptive care, but you supported legislation that would let your employers deny you contraceptive care, you might have a case of Romnesia.”

Romney continued his own new assault on what he claimed was the lack of a second term agenda for the Democratic administration, a chord he has been striking at each appearance since the second debate.

"The president has no jobs agenda. We keep on asking him: What are you going to do to create jobs? He has nothing new. He says well we're going to go forward," Romney said. "Forewarned is a better term."

“Here’s just part of President Obama’s agenda for a second term: double our exports, create a million manufacturing jobs, cut oil imports in half, recruit 100,000 math and science teachers, train two million workers at community colleges, and reduce the deficit by more than $4 trillion," Obama campaign spokesman Danny Kanner responded in a statement.

Romney and vice presidential nominee Paul Ryan's joint appearance in the Sunshine State, their third such joint stop here -- and Romney's plan to stay here through Monday night's debate -- reflect the closeness of the race here. A new poll from CNN/ORC shows the Florida in a statistical dead heat -- with Romney claiming 49 percent of the vote to Obama's 48 percent.

At a fundraiser in Boca Raton on Friday, Ryan told donors their late gifts could make the difference in financing a turnout operation that will determine the winner of this often-decisive battleground state.

"Your dollars are going straight to voter turnout, to voter education, to cutting thru the clutter, to giving the country a choice that they themselves deserve," Ryan said.
